On the MRS cluster, users can logically divide Yarn cluster nodes to combine multiple NodeManagers into a Yarn resource pool. Each NodeManager belongs to one resource pool only. The system contains a Default resource pool by default. All NodeManagers that are not added to customized resource pools belong to this default resource pool.
You can create a customized resource pool on MRS Manager and add hosts that have not been added to other customized resource pools to it.
Enter a name for the resource pool. The name cannot be Default.
The name contains 1 to 20 characters and can consist of digits, letters, and underscores (_). However, it must not start with underscores.
In the host list on the left, select the name of a specified host and click to add the selected host to the resource pool. Only hosts in the cluster can be selected. The host list of a resource pool can be left blank.
